[1] The genus name Choeronycteris is derived from the Greek words choiros (pig) and nykteris (bat).

[3] Further south, its range extends from Mexico (including Baja California and the Tres Marias Islands) through El Salvador, Honduras, and Guatemala.

[4][5] It occurs at altitudes of 300–2,400 meters in deciduous, semi-arid thorn scrub and mixed oak-conifer forests.

[1] The Mexican long-tongued bat feeds on nectar, pollen from agaves, and fruits from other plants.

[2] Its tongue can extend up to a third of its body length, enabling it to reach nectar deep inside a blossom.

[7] A key factor for migration in glossophagines over larger distances seems to be a large body size that permits storing energy for traveling over areas without available food.

[8] Following this idea, C. mexicana might be the larger, migrating version of the small, resident sister taxon Musonycteris harrisoni.

Migrating species, on the other hand, tend to focus on predictably flowering, high-quality resources (von Helversen and Winter 2003).
